We've previously written about Cameron Todd Willingham who was executed in Texas in 2004 for an arson/murder. Evidence was mounting that the fire was not arson, but accidental. See here, here, and here.

In a withering critique, a nationally known fire scientist has told a state commission on forensics that Texas fire investigators had no basis to rule a deadly house fire was an arson -- a finding that led to the murder conviction and execution of Cameron Todd Willingham.

The finding comes in the first state-sanctioned review of an execution in Texas, home to the country's busiest death chamber. If the commission reaches the same conclusion, it could lead to the first-ever declaration by an official state body that an inmate was wrongly executed.
